Volvo CE’s EC460CHR demolition excavator is supplied with both high-reach demolition boom and standard excavator configuration digging boom and arm, a changeover process that can be done in less than 30 min.

Part of Volvo Construction Equipment’s growing line of high-reach demolition excavators, the EC460CHR features a 27.4-m (90-ft) boom and arm. It has a maximum forward reach of 15.8 m (52 ft).

The excavator is supplied with both high-reach demolition boom and standard excavator configuration digging boom and arm, a changeover process that can be done in less than 30 min. Also standard is a transportation cradle for both configurations for increased greater versatility, allowing the machine to remain useful and productive beyond high-reach applications.

Volvo CE says the EC460CHR comes with enhanced engine power and torque, along with efficient slew speed and torque. The tailored hydraulic flow and pressure output of the excavator allows operators to take advantage of high-reach attachments such as pulverizers, grapples, crushers, hammers, and shears. Speed from the Volvo 245-kW (330-hp) at 1800 rpm engine is matched to hydraulic flow, maximizing efficiency on combined operations such as lifting and slewing. Maximum torque is 1820 N·m (1340 lb·ft) at 1350 rpm. Maximum attachment weight is 2.5 t (2.8 ton).

The standard hydraulically tilting operator cab leans back up to 30°, offering operators better visibility along with reduced fatigue and neck strain when working on high-reach applications. An optional, reversible fan helps purge debris and airborne particles from the coolers, reducing cleaning and maintenance time. Micro-mesh screens are also fitted to side doors and on the engine cowl.

With "demolition-grade strength," the cab of the EC460CHR is protected by a frame-mounted falling object guard and a side-impact-protection system fitted on the superstructure.

For extra machine protection, the side doors are double thickness and the boom cylinder guard shields the rods, cylinders, and piping. Undercarriage protection includes full-length track chain guards, 8 mm (0.3 in) thick under plating with bolt-head protection, an 8-mm (0.3-in) swing-ring guard, and service panels that feature recessed hinges that won’t catch on debris or their surroundings.

A modular joint system uses two hydraulically operated pins to release the digging equipment and quickly change from the high-reach demolition boom to a standard excavator configuration. The engine delivers high torque at low engine speeds, while the optional hydraulically variable undercarriage width aids transportation (when contracted) and stability (when extended). An optional boom-mounted camera also increases productivity when working on high-reach operations.

The EC460CHR features Volvo’s Care Cab, positioned on rubber mounts to reduce vibration. The sound-dampened cab offers a large, roomy, and uncluttered operator space, says the company. An easy-to-read instrument panel provides operators with an overview of all gauges, controls, and warnings. A boom-mounted total moment indicator provides a warning if the machine is approaching its maximum safe working load, and forward and rear-view cameras increase jobsite safety.

Ground level service access makes inspection and servicing quick and easy, with the ability to change the oil, fuel, and water separator filters, as well as drain the oil and access the hydraulic pump, from the ground.The cab air filter is located outside the cab for easy routine checks, while fuses are protected in a sealed, ground-level steel box behind the cab. The sloped track frame design allows for self-cleaning of mud and debris, and track links are lifetime-greased and -sealed.
